Keqi Wang c99d215c0c connector/cn_proc: revert "connector: Fix proc_event_num_listeners count not cleared"
commit 8929f95b2b upstream.

This reverts commit c46bfba133 ("connector: Fix proc_event_num_listeners
count not cleared").

It is not accurate to reset proc_event_num_listeners according to
cn_netlink_send_mult() return value -ESRCH.

In the case of stress-ng netlink-proc, -ESRCH will always be returned,
because netlink_broadcast_filtered will return -ESRCH,
which may cause stress-ng netlink-proc performance degradation.
